  To configure Xymon, the following options are available:
     --rrdinclude DIRECTORY   : Specify location of RRDtool include files
     --rrdlib DIRECTORY       : Specify location of RRDtool libraries
     --pcreinclude DIRECTORY  : Specify location of PCRE include files
     --pcrelib DIRECTORY      : Specify location of PCRE libraries
     --sslinclude DIRECTORY   : Specify location of OpenSSL include files
     --ssllib DIRECTORY       : Specify location of OpenSSL libraries
     --ldapinclude DIRECTORY  : Specify location of OpenLDAP include files
     --ldaplib DIRECTORY      : Specify location of OpenLDAP libraries
     --fping FILENAME         : Specify location of the Fping program

  The script will search a number of standard directories for
  all of these files, so you normally do not have to specify any options.
